The "Do it now" button give you the clear view to what you are doing right now.

One thing that would be awesome for me is if Doit.im could record for how long the button is active so when I press the complete box it could tell me how long I actually worked in that task.

It would be an easy way to keep track how many hours I take to complete each task.

If I could pause while I as out of the office it would be even better.
